STEP 7 (TIA Portal) displays the dialog as follows:
Figure 9-29 Adding OPC UA elements to the server interface
Limiting the view to OPC UA servers
By selecting the OPC UA elements, you limit the view to the OPC UA server and the options
of the OPC UA clients.
In the server interface of the example, the "Robot_1" data block is missing because industrial
trucks do not need access to the server methods and tags of the robot.
In this case, it is best to disable the standard server interface (SIMATIC namespace) in the
OPC UA properties of the S7-1500 CPU so that the filtered nodes cannot be accessed any
other way.
Figure 9-30
You can also disable the visibility of each configured server interface in the properties of the
server interface and thus prevent that this server interface can be used by clients during
operation. This option lets you define multiple server interfaces, for example, and download
only the required server interface.
